Hello
Don't try to correct anything, you make a mistake, you continue with it, even if it makes for a deformed result, as long as it looks 3d, even if skewed. If it is really bad, start again on a new paper (for big constructions) or on the side (for little exercises likes leaves). The point is for you to do it well on the first shot, so do more preparing and stuff to calculate how the real trajectory is supposed to be.
